STEM WINDING AND SETTING WATCH.

SPECIFICATION forming part of Letters Application filed August 14:,1889.

To all whom it may concern.-

Be itknown that I, BERNARD IIEIDBRINK, a citizen of the United States,residing at Austin, in the county of Travis and State of Texas, haveinvented certain new and usefullmprovements in Watches; and I do herebydeclare the following to be a full, clear, and exact description of theinvention, such as willenable others skilled in the art to which itappertains to make and use the same.

My invention is an improvement in Watches 5 and it has relationparticularly to an improvement in mechanism for winding and setting thewatch, so that the movement may be rendered interchangeable forapplication to a case, whether arranged for a hunting-case watch or anopen-face watch. In watches as commonly constructed a differentarrangement is made for the winding and setting mechanism of ahunting-case watch from that of one having an open face. The stem in theformer is arranged radially from the figure 3, and that of the latterbeing placed radially from the figure 12, representing time,respectively. In the drawings illustrating my invention, Figure 1 is anelevation of the face side of a watch-movement with the winding andsetting mechanism exposed to view for a crystal face. Fig. 2 is asimilar-view of a watch with the arrangement applicable to ahunting-casewatch. Fig. 3 is an elevation of the back of a watch with the mechanismexposed as applicable to a crystal-face arrangement. Fig. 4 is avertical section taken through the yoke K.

Similar reference-letters indicate like parts in all of the figures.

Referring to the drawings, K is a yoke pivoted at a in a hunting-casearrangement, and at a in the open-face arrangement, having three wingsor arms a b 0, each provided with axis-points centrally located,respectively.

A is a minute-wheel provided with a pinion a each having gear-teeth.This wheel and pinion is interchangeable for two positions in the frameof the movement, the one, as in Fig. 2, for a hunting-case arrangement,and the other, as at Fig. 1, for the open face arrangement upon the pin0 II is the winding-wheel journaled in the cock I, fixed to themovement-frame. On the side of the movement-frame opposite the wind-Patent 110.433,,289, dated July 29, 1890.

ing-wheel H is the cap L, (see Fig. 3,) the teeth of which engage thepinion f of thehandarbong. Connected with the arbor and pinv Pivoted inthe frame of the movement of the watch at the outer edge is a lever 1,provided with a forked end and a pointed end which passes through thewinding-pinion a".

z" is a lever pivoted beneath the lever t, provided with a forked endand a pin m to be engaged-by the said fork in, one of the prongs of saidfork being shorter than the other.

p is a pin projecting inward from the arm a of the yoke K and through aslot m in the movement-frame within reach of the fork of the lever t.

p is a spindle which connects with the crown M of the stem M through thelatter and within reach of the lever t. The lever i is under theinfluenceof a spring klsecured to the movement-frame, and in turn thelever t" is under the influence of the said lever 1'.

About the axis of the yoke K is arranged a gear-wheel (shown in dottedlines in the drawings) adapted to engage the windingpinion 03 00. Anintermediate gear wheel is arranged to engage the winding-wheel H andthe minute-Wheel A directly (as in the hunting-case arrangement) andindirectly through gear-wheel d d, as in the open-face arrangement. Thewheel cl is pivoted on pin at Z in the movement-frame, and a pin 0 alsoin said movement-frame, is intended to form the axis of the wheel A, asin the hunting-case arrangement.

WVhen the yoke K is fixed for the huntingcase arrangement, it beingpivoted opposite 3 of the dial, the arms or wings CL and o are bothprovided with gear-wheels. The one, d, may now en gage the wheel H whenthe crooked lever is pushed in, and when the said lever is drawn out thewheel cl will engage the Wheel A for setting purposes. It is-understood,of course, that the yoke K is rocked about its axis by the engagement ofthe short arm i with the notch 91 in the yoke, so that when the wheel dis engaged by the wheel H the wheel d is out of mesh with the wheel A,so that the pinion a will not be operative with the setting mechanism.

In the arrangement of the open-face watch the yoke K is pivoted atapoint opposite the twelve points of the dial, the arm hot the yoke Kcarries the wheel (1', and the wheel d is pivoted upon the stud Z Thestud in the arm a for wheel (I, as in the hunting-casearrangement, nowprojects through a slot m, andis in fact the pin 19, as seen in Figs. 3and 4 of the drawings. In this arrangement the spindle attached to crownM within the stem M has a movement radially to a limited eX- tent, andwhen said crown is pressed inward the said spindle comes in contact withthe lever i. The fork of said lever '6 clasping the pin m of lever 71the latter is moved, and its fork clasping the pin 19 of the yoke-arm athe wheel (1 is brought to engagement with the winding-wheel H. Drawingthe spindle of the stem out releases the lever i, which now receives theinfluence of the spring 70 As the motion of said lever i is communicatedto the lever 2", the pin 19 is pushed by the fork of said lever t" tobring the Wheel d to engagement with the Wheel d, which lattercommunicates its motion when the crown M is revolved to operate thesetting mechanism.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. In a watch, the interchangeable pivoted yoke having three arms orwings provided with a notch in one, to be engaged by a shifting-lever,and all three of said arms or wings arranged for gear-wheels, as and forthe purpose set forth.

2. The combination. with the triple yoke pivoted opposite the firstquarter-point of the dial and the gear-wheels d d, of the windingwheelH, a gear-wheel about the pivotof said yoke, the setting-pinion 0c, theminute-wheel A, a rotary spindle within the watclrstem, the cap L, andthe wheel and pinion connected therewith, as and for the purposespecified.

3. The combination, with the yoke, a gearwheel arranged about said pointas an axis, the winding-pinion 0c, the pin 13 in said yoke pro jectingthrou gh a suitable slot in the move ment-frame, the levers t' i,the spring k, and the spindle in the stem and the wheel cl in the armI), of the Winding-wheel II, the wheel I), the wheel A, the cap L, andthe pinion and wheel f h, whereby when the yoke is shifted by thewithdrawal or the pushing of the said stein-spindle the wheel cl will bebrought in proper relation with the setting or winding wheel to set orwind the watch from the stem, as set forth.

In testimony whereof I affix my signature in presence of two witnesses.

BERNARD l-IEIDBRINK.
